When turning is not sufficient to complete the work on the metal part, the so-called “reworking phase” is used for completion. Mainly milling and drilling activities are carried out using the transfer type machines. Assembling, on the other hand, can be mechanical or manual and is generally carried out for the electromechanical sector. An assembly service of screws and springs on alveoli and pins is also offered. Most of the reworking and assembly work is performed at the Guerrini Spa plant in Slovakia.
